<p>Source for IIDC (Instrumentation &amp; Industrial Digital Camera) firewire
cameras. If several cameras are connected to the system, the desired one
can be selected by its GUID and an optional unit number (most cameras are
single unit and do not require it). The frame size, rate and format are set
from capabilities. Although the IIDC specification includes a raw video
mode, many cameras use mono video modes to capture in Bayer format.
Thus, for each mono video mode supported by a camera, both gray raw and Bayer
corresponding video formats are exposed in the capabilities.
The Bayer pattern is left unspecified.</p>
